Long probe tip
3.5.3 Functional principle
The probe tip directs the ultrasonic waves from the measurement location to the ultrasonic
converter.
The ultrasonic converter converts structure-borne sound waves (vibrations) into an electrical
signal over a large frequency range. This electrical signal is already amplified and digitized in
the sensor. The further data processing and output is carried out in the measuring device.
The integrated infrared temperature sensor quickly records the surface temperature of the
measured object in a non-contact manner. The size of the optical detection field depends on the
space between the sensor and the measured object.
The LED lights serve as a flashlight and make it easier to couple the sensor to the
measurement locations in poorly lit environments.

Application
Bearings Use if no smooth coupling
surface is available.
Use as a manual sensor,
for quick comparative
Condensate Use on hot drains, to
separator create distance between
surface, sensor and user.
Use on drains behind
covers, grilles, where
there is a greater distance
from the surface.
Condensate The pump housing must
separator be freely accessible.
Operation of the device, sensor system and apps
Conditions
testing.
To be observed
Search for the
measurement location
with the best transfer,
such as grease nipples or
screw connections of the
bearing housing.
Depending on the
surface, it is possible to
penetrate the paint layer
with the tip to some
extent.
Attach the sensor at the
points where the actual
valve is installed inside
the drain. This is where
the best ultrasound
transfer is available.
With regard to
comparative
measurements, always
reattach the probe tip to
the same test point.
